Part T:Hyarates Hydrates are crystalline compounds in which one or more molecules of water are combined with each formula unit of a salt. The water is not bound tightly and can usually be driven off by subjecting the crystals to the hottest flame of a Bunsen burner for 5 to 10 minutes. If the hydrate is colored, a color change usually results upon heating as the anhydrous salt forms. For example the following change occurs upon heating: CuSO4·5H2O (s) bright blue CuSO4 (s)+5 HO (g) white A generalized form of this reaction is: CuS 04.xH2O(s) CuSO4 (s) + â x H2O(g) Recall that the percentage of a component in a compound is calculated by: (Part/whole) x 100=% Preliminary Questions (5 p Describe how you could find the % by mass of water in the hydrate CuSO4·5H20 assuming that yo did not already know the formula. Be specific and list the laboratory procedural steps you would t in the order that you would perform them.
